Traveling grate



Dec; 14 1926*.

w. R. WOOD TRAVELING- GRATE Filed August 5, 1923 2 Sheets-Sheet MVA/fis A TTORNE YS equal and opposite tendency of the other rollers. The net eect of the rollers is such as to prevent the links from separating transversely of the chain, thus preventing the opening up of objectionable gaps With an area over and above that which is normally intended to exist between links. rThe advantages of this, in operation, will readily be appreciated by those skilled in the art. The rollers are journaled in bearings 12a which are free to slide in a direction transverse of the grate. As a result, While the links over a roller are pressed together toward one end thereof, the roller as a Whole is free to shift in anV opposite direction under the general pull on the grate, so that there is. no net lateral displacement of the grate at any point.

The general principle upon which the invention proceeds is that the supporting members or surfaces are such that, considering any given point thereof, such point, in moving, will travel toward a side of the grate during the interval of contact, while at the same time there is in reality no lateral displacement of the grate as a Whole. It Will be obvious that this principle may be realized by other than the specic arrangement shown.

As heretofore pointed out, the arrangement is so effective in operation that it is possible to increase the width of the chain grates almost Without limit, Without running into -the difficulty of opening up undesirable gaps between the links.

llhat I claim is:

l. The combination With a traveling grate composed of a plurality of elements, of a supporting surface for engaging them moving toward a side of the grate.

2. The combination with a traveling grate composed of a plurality of elements, of a plurality of supporting surfaces for engaging them, alternate surfaces moving towards opposite sides of the grate, during operation.

3. The combination with a traveling grate composed of a plurality of elements of a support therefor tending to cause movementof the elements toward a side of the grate.

fi. rlhe con'ibinationwith a traveling grate composed of a plurality of elements, of a plurality of supports tending to cause movement of the elements alternately toward opposite sides of the grate.

5. The combination with a traveling grate composed of a plurality of elements, of a roller for engaging them extending across the line of movement of the grate and at an inclination thereto.

G. The combination with a traveling grate composed of a plurality of elements, of a plurality of rollers for engaging them en tending across the line of movement of the grate and alternately, oppositely inclined from a perpendicular thereto.

7. The combination With a traveling grate composed of a plurality of elements, of a plurality of rollers for engaging them e3-r tending across the line of movement of the grate, and alternately, oppositely inclined from a perpendicular thereto, together with means preventino` displacement of the grate.

8. The combination with a traveling grate composed of a plurality of elements, of a plurality of rollers for engaging them eX- tending across the line of movement of the grate, and alternately, oppositely inc l from a perpendicular thereto, together v' means on the rollers preventing displacement of the grate.

9. A chain l gratercomposed of a plurality of links, in combination With a roller for engaging them, said roller being' set at anV oblique angle to the line of movement of the grate. 1

ln testimony whereof, I signed my name.
